The following code finds out the factorial of a number. There is some error in it.


#include
int main ()
{
long number;
std::cin>>number;
std::cout<< factorial (number);
return 0;
}
long factorial (long a);
{
for(int i=1;i<=a;i++)
fact=fact*i;
}

Answer 1

Answer:

using namespace std

Explanation:

#include <iostream>

int main()

{

  int n=5, fact=1,i;

  for(i=1; i<=n;i++)

     fact = fact * i;

  cout<<"Factorial of "<<n<<" is "<<fact;

  return 0;

}

For this the output  is 120
